STEM WINDING AND SETTING WAT CH.

SPECIFICATION forming part of Letters Patent No. 484,359, dated October11, 1892.

Application filed February 20, 1892. Serial No. 422.272. (No modclJ TaZZ whom it may concern.-

Be it known that I, JOHN E. FULTZ, a citizen of the United States,residing at Coatesville, in the county of Hendricks and State ofIndiana, have invented certain new and useful Improvements in StemWinding and Setting Watches; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in pendant winding and settingwatches, the ohject of the invention being to simplify and strengthenthe mechanism in order to produce a watch that will be cheaper tomanufacture, will be more durable and less liable to get out of order,and that can be repaired with greater ease and less expense.

The object, also, is to provide a stem winding and setting mechanismthat can be applied to any Watch, especially to watches of Americanmanufacture.

The invention consists, primarily, in an oscillating plate carrying atoothed wheel journaled on the same arbor to which the oscillating plateis pivoted and meshing with a bevel gear-wheel on the end of thependant-stem and with wheels to each side on the ends of the oscillatingplate, one of the said wheels at times meshing into and driving atoothed wheel fixed upon the winding-arbor to wind up the mainspring,and the other at times meshing with a toothed wheel connected with thehands-arbor.

The invention also consists in the construction and arrangement oflevers to shift the oscillating plate by pulling out the fluted knob onthe end of the pendant.

The invention also consists in certain details of construction, such aswill be fully described, and pointed out in the claims.

The objects of this invention are accomplished by the mechanismillustrated by the accompanying drawings, in which- Figure 1 is a detailshowing inside view of the plate of a watch-movement having myimprovement. The barrel for the mainspring is shown broken away tobetter illustrate the construction, and only such parts of the mechanismof the works necessary to a good understanding of the construction andtached.

application of my improvement are shown. The positions of theoscillating barand wheels on the opposite side of the plate are shown indotted lines. Fig. 2 is a view of the opposite side of the plate fromthat shown in Fig. 1. The position shown in Figs. 1 and 2 is thatassumed in winding up the mainspring, the

dotted lines in Fig. 2 indicating the position of the wheels andoscillating plate for setting the hands. Fig. 3 is a detail view of thelevers for shifting the oscillating plate, the full lines showing theadjustment for setting the hands and the dotted lines that assumed forwinding the mainspring. The size of the levers is exaggerated to betterillustrate the construction. Fig. 4 is a vertical cross-section throughthe line a: as of Fig. 1; and Fig. 5 is a detail showing theconstruction of the double-cam lock for securing the pendant-arbor bymeans of the intersecting-lever, upon which the cam operates.

Similar letters refer to like parts throughout the several views.

A is the plate of the watch-works, to which the various parts of myimprovement are at- It is of usual construction.

B is the barrel, within which the mainspring of the watch is inclosed.It is geared to the operative parts of the watch in the usual manner.

13 is the arbor of the barrel and is projected through the plate A andis provided with a toothed wheel B on the opposite side of the plate.

O is the arbor to which the index-hands are attached, and O apinion onthe same side of the plate A as the wheel B and turning with the arborC, but not meshing with the wheel B D is the oscillating yoke on thesame side of the plate A as the wheels B and 0. Its arbor D is integraltherewith and is projected through the plate A a suitable distance togive engagement to the lever D which lever is provided with a squareopening or hole to receive the correspondingly-shaped shank of thearbor, which is inserted in the said opening so the movement of thelever D will move the oscillating plate in like manner. Looselyjournaled upon the arbor D between the plate or yoke D and the plate Ais a toothed wheel D The inner half of the teeth on the wheel D arebeveled to mesh with the cogs on the bevel-wheel D on the lower end ofthe pendant-bar E, and the remaining portion of the teeth are straightto mesh with the teeth of the cogged wheels at and d. These wheels d andd are arbored to the outer ends, respectively, of the oscillating plateD, and the inner ends of the arbors are projected through suitableopenings made for that purpose in the plate A, which openings serve asguides to prevent the displacement of the arbor. The wheels (Z and d arein constant engagement with the wheel D and are so proportioned andarranged that in certain positions the wheel d will be in engagementwith the toothed Wheel on the barrel and in certain other positions thewheel d will be in engagement with toothed wheel F. The toothed wheel Fis in constant engagement with the wheel C on the hands-arbor. Asuitable spring G presses the wheel 61 into engagement with the wheel Bof the barrel unless otherwise restrained. When it is desired toovercome the action of the spring G, as in setting the hands, it will bedone by means of a spring-catch H, which will engage the end of thearbor of the wheel d, which is projected through the plate A andcontacts with the spring H. A shoulder h is formed on the spring H, andthe end of the arbor is squared to fit into the shoulder, and both areso adjusted that when the wheel d is thrown down into engagement withthe toothed wheel F the squared shank of the arbor will drop into thenotch or shoulder on the spring and will be securely held until thespring is forced back sufficiently to release the arbor when the latterwill return to the position acquired by the action of the spring G onthe wheel d. The lower end of the pendant-post E is square incross-section and is .inserted into the elongated hub of the bevel-WheelD and by rotating the pen dant-post E the wheel D will be actuated. Thewheel D is journaled to the plate by means of the boxing A The operationof the oscillating plate D is controlled from the pendant-rod E in thefollowing manner: A notch 7c is formed in the rod, and a lever M,pivoted at m to the frame A, is placed in this notch, so that a verticalor longitudinal movement of the rod will oscillate the lever. Attachednear the pivotal point to the lever is an arm M, having a foot m, whichbears against the spring H and when the lever is lowered presses thespring back out of contact with the projected end of the arbor d,thereby releasing the arbor. The opposite end of the lever M ispivotally secured to a link P, which in turn is pivotally secured to theend of the lever D on the arbor D, so that the raising or lowering ofthe lever M will oscillate the yoke or plate D, so that the adjustmentfor winding or for setting the watch is brought wholly within thecontrol of the pendant-stem.

The operation of my improved mechanism will be apparent without furtherdescription.

WV is a double cam whose cam-faces contact at times with the lever M andact like a screw-thread to shift the lever into and out of the notch inthe pendant-rod. This is for convenience inv removing or inserting thependant-rod.

I claim 1. The combination, with the lever M, pivotally secured to theplate of the works and having an arm 1/ for the purposes described, ofthe pendant-rod E, notched to engage the lever, link P, lever D andattached plate D, carrying the wheels D d, and d, the spring G, and thespring H, with its shoulder h, and the squared arbor d, all for thepurpose of producing a mechanism that can be changed automatically froma stem-winding to astemsetting device and the reverse, subject to thecontrol of the pendant-rod.

2. In combination with the oscillating plate D and its wheels D, d, and(1, arranged with relation to the hands-arbor and the windingarbor, andthe lever D the lever M, link P, and the pendant-rod K, arranged andoperating as shown and set forth.

In testimony whereof I affix my signature in presence of two witnesses.
